This study approaches the question of the administrative procedure of the environmental licensing of ranks of fuel resale, taking as basis a study case of the reality of the City of Natal/RN (Brazil). For in such a way, it was done a retrospect on the evolution of the system of road transport in Brazil, having started to briefly analyze the urbanization process that if after accented in the capitals of the Brazilian States the decade of 1950, relating these subjects with the growth of the sector of fuel resale. After that, it was transferred boarding of the defense of the national environment to the light of ambient principles constitutional. In the sequence, a boarding on the ambient guardianship in the Federal Constitution of 1988 was made, treating basically specifies and on the national urban politics and the national politics of the environment, with its instruments. In the sequence, it was transferred the analysis of the abilities and attributions of the National Advice of the Environment (CONAMA) and its Resolutions, for then only enter in the most important part of this work: an analysis of the environmental licensing of ranks of fuel resale, in the reality of the City of Natal/RN. Before this specific boarding, it was proceeded specifically a survey and communication from the applicable norms to such establishments (Resolutions of the CONAMA and norms of the ABNT), for after that carrying through an geo-ambient characterization of the City of Natal/RN. Finally, a reflection was made on the possibility of magnifying of the state activity, in terms of guarantees for the responsible members for the environmental policy and of administrative efficiency, through the idea of the ambient regulation. For the accomplishment of this study, it was proceeded research in diverse sources such as books, magazines, sites of the Internet, periodicals, thesis and dissertations, among others material, beyond visits the agencies that direct or indirectly act with the ambient defense and as fuel resale, such as Secretariat of Environment and Urbanism of the City of Natal (SEMURB), Institute of Economic Development and Environment of RN (IDEMA), Brazilian Institute of the Environment and the Natural resources You renewed, Executive Management of RN (IBAMA/RN), Public prosecutor's office of the Environment of Natal (Public prosecution service of the RN), National Agency of Oil (ANP) and Union of the Retailing of Derivatives of Oil of the RN, among others. To the end, satiated regulation is observed that although on the substance of the ambient licensing in ranks of fuel resale, also with federal, state and municipal norms, the municipal Public Power is very far from the fulfilment of its institutional functions, in the question environmental policy of these establishments, a time that few are the permitted ranks of resale in the city of Natal/RN

O cultivo de espécies de ostras do gênero Crassostrea está em expansão no nordeste do estado do Pará, Brasil. Este estudo analisa a qualidade sanitária das ostras e da água em que são cultivadas nos municípios de São Caetano de Odivelas e Curuçá. As coletas foram realizadas mensalmente entre junho de 2009 e maio de 2010. As amostras de águas foram coletadas nas marés enchente e vazante, e cerca de 15 ostras foram obtidos a cada mês durante a maré vazante. Concentrações de coliformes foram determinadas usando a Técnica de Fermentação de Tubos Múltiplos, seguida pela identificação bioquímica das bactérias e determinação do perfil de suscetibilidade de Escherichia coli isoladas a partir de amostras de águas e ostras. A média geométrica das concentrações de coliformes termotolerantes na água foi de 119 mL MPN/100 em São Caetano de Odivelas e 163,21 MPN/100 mL em Curuçá, valores bem acima do limite de 43 mL MPN/100 estabelecido pelo Conselho Nacional do Meio Ambiente Brasileiro (CONAMA). Como a legislação brasileira relacionada à qualidade sanitária dos moluscos bivalves destina-se apenas ao produto processado, foi adotada a legislação da União Europeia, que classifica as ostras para o consumo cru em três classes sanitárias. Em São Caetano de Odivelas, apenas duas das amostras coletadas durante este estudo foram atribuídas para a classe A, sete amostras para a classe B e três amostras para a classe C. Enquanto em Curuçá três amostras foram atribuídas à classe A, sete amostras para a classe C e duas amostras para a classe C. Os resultados sugerem a necessidade de medidas mitigatórias para garantir a qualidade sanitária das ostras, tais como a aplicação de métodos de depuração.

The environmental movement rises up strongly in the year 1972 with the Stocolmus Conference, in the middle of pressions concerning the environmental preservation, in consequence of the environmental catastrophes. In spite of the fact that, in Brazil, the environmental movement has is institutionalization with the 1988 Constitution, in a way that the councils became democratic spaces, and provided the society’s participation in the management of public policies. In this way, we propose a discussion about the participation and the exercise of the citizenship in the State Council of Environment of Rio Grande do Norte (CONEMA), focusing the glance about the decisory process, as from the expression of the social actors. For that, our research compilate documents of the meetings of the referring council, transcribing the main discussions about the environmental necessities which were important in the potiguar society, and checking how these agents defend their interest during the meetings. We understand, with these informations, the role of CONEMA/RN as a communicative mechanism between State and Society. With the analysis of the informations of the extraordinary meetings from 2007 to 2014, we concluded that the CONEMA is a council where the civil organized society takes part on the decisory process, despite the great influence of the representative actors of public power over the representative actors of civil society. The results of this research confirm the discrepancy between the participation of representative councilors of civil society in CONEMA/RN. The conclusion point out that the civil society representative don’t, yet, assimilate the citizen duty, the responsibility of it1s action, producing, in this way, damages for the legal structure of the potiguar environmental legislation, with serious consequences on the public policy implementation

The objective of this paper is to investigate the physical and chemical quality of the water of the Descoberto River during the dry and rainy seasons by measuring pH, temperature, electric conductivity, total dissolved solids, turbidity, color, alkalinity and NO3-, SO42-, PO43-, NH4+, Cl- and HCO3-, and the elements Sr, Mo, Cd, Y, Ti, Ca, V, Mg, Fe, Si, Ni, Zr, Cu, Al, Cr, Mn, Ba, Co, Zn, P, Na and K. The results showed high concentrations in both seasons, with dilution along the course of the river, minimizing for a while problems that compromise the quality of the water of this source. However, a progressive deterioration can occur due to an increase in the discharge of pollutants, resulting from population growth, agricultural activities and other factors.

Environmental Laws and Regulations to dump wastewater are increasingly relevant and, together with pressure from environmentalists, provide awareness of academics in search of solutions. In Brazil, federal law, through Resolution No. 357 of 17/03/05 of the National Environmental Council - CONAMA, in Article 24 deals with the disposal of these effluents. Water pollution with heavy metals is concern because of the difficulty of the treatment and removal from the environment. Copper, for example, is a metallic element and in the form of salt is very soluble in water which dificults its removal. In this context, this study aims to evaluate the extraction of copper with acrylamide polymers through the process of assisted flocculation followed by filtration. Therefore, we used acrylamide polymers, produced by SNF Floerger, with varying degrees of ionicity which is the parameter examined on the extraction of copper. We used the FA polymers FA 920 SH, AH 912 SH, AN 905 SH, AN 910 SH, AN 923 SH, AN 945 SH, AN 956 SH and AN 977 SH, which have anionicities different from each other and growing in that order. The parameters temperature, pH, concentration of the copper solution and stirring speed are fixed. The polymer solution was added to a solution of 200 ppm copper, varying the concentration of polymer. After stirring, an assisted flocculation occurred followed by filtration of the effluent. The filtrate was analyzed by atomic absorption spectrophotometer and the percentage removal of copper ranged from 63 % to 97 %, noting that polymers with higher ionic charge were responsible for the highest percentage of copper extraction. The results of this study showed that these polymers can be applied in the treatment of wastewaters containing metals such as copper
